Abstract: A microfluidic, chip-based assay device has been developed for measuring physical properties of an analyte (particularly, whole blood or whole blood derivatives). The technologies can be applied to measure clotting times of whole blood or blood derivatives, determine the effects of anticoagulant drugs on the kinetics of clotting/coagulation, as well as evaluate the effect of anticoagulant reversal agents. These technologies can additionally be used to optimize the dosage of anticoagulation drugs and/or their reversal agents. The assay is independent of the presence of anticoagulant; clotting is activated by exposure of the blood sample in the device to a glass (or other negatively charged material such as oxidized silicon) surface, which activates the intrinsic pathway and can be further hastened by the application of shear flow across the activating materials surface.

Abstract: A file namespace hierarchy bypass and method to access files are provided. The bypass can be employed, for example, as a computer-readable medium with instructions for generating a unique identifier associated with a file and instructions for accessing the file based on the unique identifier and a specified search space. A computer-readable medium having instructions for obtaining the unique identifier and specified search space associated with the file and instructions for generating a path designation by combining the unique identifier and the specified search space used to access the file may also be employed. The method for bypassing the namespace hierarchy of the file, for example, may include passing the unique identifier and specified search space to a program and accessing the file based on a path designation generated by the program by combining the unique identifier and specified search space.

Abstract: A file stream exchange system and method are provided. The system can be employed, for example, with a storage system that supports transactions as a primary mechanism and employs a rich type system. The system provides a mechanism for the storage system to provide reliable updates to file streams while preserving the common criteria for security. The system employs a unique way of remapping the file-streams associated with the file-backed items that eliminates the need for copying over basic attributes, security information and timestamps etc. Significantly, the system does not rename the files involved in the operation nor does the system rely on attribute tunneling to copy over any subset of attributes for the completion of the task. The system includes a replace stream component which is a kernel mode mechanism that allows transactional exchange of stream data of two file-backed items without violating the common criteria for security.

Abstract: A technique is provided whereby a stream of data located in a first storage location is registered for migration administration and according to preset criteria, portion(s) of the stream of data that are suited to another storage location are migrated to maximize system storage efficiencies. The file system may have use of facilities that enable the monitoring of files/streams that have been registered for migration administration or files/streams may be polled according to preset criteria. If the stream of data has portions to migrate to another storage location, the hierarchical storage management (HSM) system migrates the data to the other storage location, such as to long term or off-line storage, and preserves the data relationships of the stream via metadata. The technique allows for multiple volumes to be spanned by the migration target location, and multiple file systems may service the source and target.
